LOOM.

- T all 107mm it may concern `Be it known that-I, CHARLES :l-LANE, a citizen of the United States, residing at Knoxville, in the county of Knox and State of-'lenne-ssee, have invented a new and use# ful Improvement in Looms, of which the following 1s a specific-ation,- reference being had to the accompanying drawing.

My improvement relates particularly to lcloth weaving looms having bobbin maga# yzines or batteries similar to the No. 3' Northrop batteries on looms manufactured by the Draper Company, of Hopedale, Massachusetts. l

The object of the improvement is to provide more eicient means for clamping and' parting or cutting the filling thread between the cloth andj the empty or nearly empty bobbin which is to be discharged from the shuttle and, give place to'ia new bobbin from the magazine or battery. For Such cutting, looms ofv this type havethread clamping and parting- 1nStrument-alities .comprlsing 4knives and accessories located `between the cloth and the battery, which instrumentalities are moved automatically to the path of the thread when the reduced `quantity of thread on the bobbin allows a @bobbin feeler7 to set a starting rod into motion, the knives being made to cut by the action of the bunter upon one of the knives, the bunter being mounted on the lay in position to 'engage and move a part closely associated with one of -the knives when the lay reaches its forward posit-ion, the position occupied by the lay when ,the bobbins are to be transferred. This lea'ds to the 'clan'iping and parting or cuttingof the thread as often as motion is 40 transmitted fromthe shuttle feeler for moving the knives to the thread path. As a consequence, the thread is at times clamped anilparted or cut when the bobbin is not changed, so that the nearly empty bobbin remains in' the shuttle and is carried back and-forth by the latter without paying outv filling thread into the warp, which action causes defects leading to the grading of the .cloth as second. This defect is always objectionable andespccially so in the higher Ygrade and expensive cloths. y Failure to d'scharge a bobbin from the shuttle, and put anotherl irito its place may be l due to any one of several causes. For-rex- Speccation of Letters Patent.

ample, .the portion of the battery imme- 'diately'above the shuttle may, on account of so changed as to retain the bodily move-jl ment of the clamping and parting instru!A mentality or knivesl and their accessories to and from the thread path and to actuate the movable knife to clamp'and part or cut the thread only when the bobbin leaves the shut tle and another enters from the magazine. Thus the bobbin in the shuttle does not travel with a cut thread, and the shuttle does not travel without yaV bobbin, for the bobbin in the shuttle is forced outward only by the downward pressure of a new bobbin taking its place in the shuttle. words, the clamping and parting instru-I lmentalityv is actuated through thel movement of a bobbin out of the magazine into the'shuttle. It is the bobbin in the magazine which rocks the bobbin support.

My improvement involves the making of a combination which includes means for transmitting motion to the movable knife from a bobbin passingdownward fromy'the magazine into the shuttle. As a practical example ofl such an embodiment of my invention, I describe herein .the bobbin support as Aa portion of the mechanism forming such connection between the knifeand the bobbin beingdischarged from themagazine, vsuchv bobbin support being a' spring-controlled rocking member heretofore applied below ythe'lower portion of the inner end of thevmagazine in proper posi-v tion to receive and support the end of thev bobbin adjacent the knives when thebobbin reaches its position abovel the shuttleiboxi, the inner fdisk of the magazine being surrounded by a stationary flange which serves to hold the inner endsof 'the bobbins in,

In other notches in said disk until the bobbin reaches such position above the shuttle, at which place said flange is omitted and its place taken by the. tilting or rocking bobbin support, which support is held in its normai. position by a spring and driven out of position by said bobbin when sufficient downward pressure is placed upon the latter by the mechanism heretofore used in such loon'is for driving such bobbins down ard ln the accompanying drawings, Figure l is a front elevation of a bobbin magazine or battery and accessory parts, the thread guide and holder and other portions being omitted; Fig. is a section on the line, 2 2, ot Fig. l; Fig. 3 is a section on the line, 3-3, of Fig. l; Fig. e is a section in the upright plane in which the bobbin support spring bolt lies; Fig. 5 is a section on the line, 5---5, ot Fig. 4, looking downward; Fig. if? is a detail plan of a portion ofthe knife actuating mechanism; Fig. 7 is an upright section on the line, 7 7, of Fig. 6, looking in the direction ot' the arrow; Fig. 8 is a section on the'same line, vlooking in the opposite direction, the left-hand portion of said. ligure presenting the clamping and parting members; Fig. 9 is a section on the line, Stm-9, of the Fig. 8, looking in the direction of the arrow; Fig. l() is a section on the line, 10-10, ot Fig. 8, looking in the (,lirectionof the arrow; Fig. ll is an elevation ot' the left hand end of the clamping and detached from the other parts.

Referring to said drawings, A1, is a porA tion of the right hand loom side. This and the lett hand loom side (not shown) sup;r port the breast beam, A, only the right hand portion of which is shown. The two looms are joined .to each other by the breast beam and the liront and rear girts (not shown). rThe magazine or hopper is shown supported by the breast beam. rllhe shuttle lceler and thread arm are shown supported on the right hand loom side.

)'"or conrenicnce in description, the portion ot the machine to which the magazine applied and at v-.fhicb the loom side, l 1, located will be regarded herein as the it hand side ot the machine, while the po tion olE the machine at which the breast beam is located will be considered the 'front :ri" the machine, and movement toward the :Front o'l the machine will be called forward y and movement in the opposite direc- 'in will be called rearward.

i, ne hopper stand. l, has a foot, B2, rest-v ing upon the breast beam, fr. A. bolt, B, and a bolt'A i'l. extend through said toot, and engage .the bre; t beam, whereby the hopper #taudis rigidly secured. The bobbin f l, extends toward the right from et the hopper stand and is rigid the center parting mechanism shown in Fig.'S;1 l2 1s a trout elevation of the upper..

thereon. On said stud is located a sleeve, BG, held in place by a nut, B1, threaded on the stud. On the left hand end of said sleeve and rigid therewith is the bobbin disk, B8. Said disk has peripheral notches, B. The hopper stand has a flange, B10, extending over the edge of the bobbin disk, eX- cepting at its lower portion. The bobbin disk has on its right hand face a ratchet tooth ring, B11. On the outer, right-hand end of the sleeve, B, is the small end disk, B12. On the left hand or inner face of the small end disk are radial bobbin holders, B13. corresponding in numberand position with .the notches, B, in the bobbinlibox.

lThese bobbin holders are plates supported yieldingly ina radial recess, B14, by expanding coiled springs (not shown). Each such iholder receives the small end of a bobbin,

C1, the large end oil the bobbin resting in a corresponding notch, B9, in the bobbin.

disk, BS.

In the opening in the flange, B1", is a horizout-al, lower flange, B11, at the rear of which is a space between it and the rear, lower end of the flange, B1". Mounted on! the rear end of the flange, l 11, is a bobbin guide, B18. Rearward of said bobbin guide is the bobbin support, B1, which is journaled on thehorizontal shaft, B2, extending through an ear, B21', cast integral with the hopper stand. yThe space between the forward end of the bobbin support-and the rear face of' the bobbin'gui'de is smallerthan the larg'eend of' a. bobbin,so that when, yby the rotation of the disks, B8, and B12, a bobbin is brought to said support and guide, the head of the bobbin can not pass between said snide and support, but mustI rest .upon the `atter until said support is depressed far enough to make said 'opening large enough for the downward passage of the head of the bobbin. At the left ofthe hopper stand is an ear,AB'-2, in which isa slide bolt, B2,

bearing against 'an upward extension, B24, 110

on the bobbin support. Said bolt extends through said extension and has a head'resting against the outer or front face of said extension. At its opposite end said bolt has a head and between said head and the ear, 115

ance oi" said spring and causes the tilting or' la@ lOt as to make the pas- M5 the bobbin holder and the downward movey ment-of said end. Such downward pressure upon the bobbin support isy exerted upon said holder through the bobbin resting upon said support as 'will be hereinafter described. At the Atime such downward pressire is exerted upon said bobbin, the shuttle, C2, (Fig. 2) is in position directly below said bobbin to receivethe latter. The downper4 stand is a horizontal sleeve, D1, in which rests the transfer stud, D2, secured rigidly by a set bolt, D, extending through said sleeve and binding said stud. Loosely surrounding said stud is a sleeve, D4. and rigid ori said sleeve is the'transferrer, D5, which is in' the form of a hammer adapted to strike down Yard upon the large end or head of the bobbin which is to be discharged from the magazine into the shuttle. On the outer end of the transferrer 1s a fork, D, extending` parallel ,to theftransfer stud, D12, until it opposite the outer portion of the lower bobbin and thence downward into position to strike the small end of the bobbin approximately simultaneously with the striking of the head of the bobbin by the transferrer, D"'. A coiled spring,vD2, Surrounds the sleeve\, D1., and has one end secured to a collar, D2, rigid on thestud, D2, and having its other end'engaging the transfiera-er, D5, for the purpose of turning the atter upward and forward. away from the bobbin support into the normal or re'st position. 0n the sleexl'e, D4, is a downward directed fork, D1.','in which rests a shaft, D11. An ear, D12, surrounds said shaft between the arms of the fork and is keyed to said shaft and supports the latchstand, D13( Said latch stand -supports a latch finger, D11. On the latclrfinger is a horizontal lateral wrist, D11. The wrist, D15, connects witlrthe latch setter as will be hereinafter described. l

The magazine rotates clock-wise, as viewed from the right of the machine, by stepstequaling the distance between the axes'of adjacent bobbins. The teeth on the ratchet tooth ring, B11, are the same in number as the notches 1n the bobbin dlsk. A hold back pawl, B211, is pivoted to the hopper stand in into the path of the ratchet teeth. i lVhen' the,

transferrer is returning from itsdcwnward' stroke, said pawl engages one of the ratchet teeth and pushes forward and upward, the range of movement being far enoughto turn the magazine far enough to bring a new bobbin abovethe discharge throat. The transferrer is driven downward by the forward movement of the latch finger, D11, when the bunter, D11, on the lay', D, is Iarried forward by the for 'ard movement olf the lay. v -V Below the breast beam, A2, the shuttl feeler bracket, E1, is secured to the left.

hand face of lthe right hand loom side, A1,

',by means of bolts, E2. A bolt, E, extends throughthe rear, end of said bracket and through a bushmg, E1. and binds said bushing to said bracket. The shuttle feelcr,;1*)",`

has a hubk surrounding said bushing and ,sh'orter than the latter so that said hub may l)move endwlse' on sald bushmg.

On the forward portionof the bracket are two diagonal arms, E1, between which lies the neck of the shuttle feeler. Said arms incline toward the right, so that when said neck rises, it and the entire fecler ,are forced rightwardl .The latch setter,` E, is rigidly secured to the shuttle feelcr rearward of the arms, E1, 'and `extends horizontally across the loom side and then'forward. The

lfor vard-,turned portion has a slot., E",

which receives the wrist, D1,- on the latch finger, D14. rlhe relative arrangement and dimensions of these parts are such as to bring the latchfinger into its lower or dcpressed position when the shuttle feeler is in its yforward or rest position. W'hcn the shuttle feelcr is moved backward, by the means to be hereinafter described,- the latch setter moves rearward and upward and cor- 'respomlingly moves the wrist, D12, whereby the latch is rotated on the shaft, D7, until the rear end of the latch finger is in position to be met by the bunter when the latter moves forward. This movcmentof the latch, it must be observed, is.indcpendent of any movement of the transferrer, D2, on the transfer stuib D2. When the bunter vmoves forward, it strikes the end of the latch finger and forces'the entire latch bodily forward, whereby the transferrer is turned on the transfer stud, the rear portion or head of the transferrer striking downward.upon the bobbin which is to be '-dischargial from thc n'iagazine.

The shuttle feeler'is turned rearward out of its position of rest by mot-ion transmitted from the, starting rod notf shown) throl'l'gh an arm (not shown) supported on the starting rod. The left hand portion of said rod is 'connected with a reciproeatory bobbin feeler which during each reciprocai tion of the shuttle across 'the loom' reaches into the side of the shuttle and bears against 130 shown) is so applied as to tend to draw saidthe filling on the bobbin. llVhen the filling on the bobbin is reduced .to a chosen quantitty, said feeler causes oigpermits a partial rotation of said starting rod (which is a rock shaft-l in the proper direction to lift said arln. Said a 'm engages the wrist, E28,

,which is rlgid on he shuttle feeler, forward of the hub of the latter. A spring (not wrist downward. When the starting rod turns from its position of'rest, said arm is raised, iwhereby the Wrist, E28, is raised, whereby the shuttle feeler is moved rearward out of its position of rest to the thread path. ready for cutting theI thread and in position to prevent the shuttle from movving endwise toward the cloth after the shuttle 'aas assumed its position beneath the magazine. i I

The upper, rear portion of the shuttle feelerextendsjnto lthe shuttle path when -the feeler is-in its rearmost position and 'the slgttxle .and the Ilay are 1n the for- '.ward position or at front center. 25.

shuttle-,freier has a notch, Ew, to receive thev filling thread when the shuttle, approaches. the position to ne\v.'laobb in. The recess, E, in the left handy lside of the outer portion of the shuttle feele'rv receives a lower filling knife, E12.

Thefupper filling knife, E, is pivoted on aA screw stud, E, extending horizontally from the left hand side of the shuttle feeler, the jaw of said knife standing, when it is in its rest position, far enough above the lower knife to readily receive the filling thread between said knives. At the left of the upper knife is the filling knife guide, El,

The screw stud, E, also extends through said guide. At the left of said .guide is a spring washer, El, surrounding\said stud. 'l`he head of the screw stud bears against said` washer and causes the engagement of the latter with the guide. Forward of the screw stud. EN. is a stud, E, extending rigidly toward the left, from the shuttle feeler into a large opening, E, in the upper knife,l Ei", and into' an opening. E, in the.

. guide, E, the latter opening being of about the same` diameter as the stud, E, so that the guide can not rotate on thc screw stud while thelarger opening, ll, in the upper knife permits rotation ofthe upperlkuife on the screw stud.

block, E2, is secured by its a short distance and there supports an upper trip pin or wrist, Ei", extendinghorizontally toward .the right. At its lower end, said block bears a similar lower trip pin or wrist, E. extending toward the left. The upper trip pin is engaged and lifted for moving the. upper edge of the cutting knife downward. This occurs while the shuttle feeler T he receive the lower end to the forward portion of lthe lefthand side of ythe upper knife and extends thence upward is in its rear position-thel position at the ,I

thread path. l'The other trip pin is engaged and moves downward for tilting the upper knife` in theoppositev direction'so as to raise its cutting edge away from the cutting`l edge of the lower knife ready toreceive the filling l thread. Such movement is imparted to the lower trip pin while the shuttle feeler is moving rearward from its position of rest; In the path of said wrist is the trip, E23.

'Said tr1p is pivoted on a screw bolt, E24,

supported by the thread holder arm, E23, and a coiled spring, E25, is coupled to said trip to tend to raise its forward end. The trip has an upper or oblique face, E27, over which the lowertrip pin mustpass when the.

upper knife is in the closed position, and the feeler moves forward to its position of rest. This involves the depression of said trip and the partial forward tilting of the thread holder arm, E28, on its stud, E2, against the stress of the contracting spring, E30. This is the normal action. `The knives are to be opened when the shuttle feeler moves in the opposite direction toward the thread path.

Then the wrist passes beneath the trip and 'is forced downward by the latter. This leaves this wrist in position to let the shuttle feeler go through any number of reciproca.-

tions with no further movement of the wrist,V

so lowered, vand consequently there is ,no closing of the clamping and parting means until the clamping and parting means closing mechanism next described is put into action. Said closing mechanism, which, in. the form illustrated by the drawings, includes the upper trip pin, E, constitutes the new portion of the mechanism herein described. The mechanism thus` far herein described, excepting the upper4 trip pin or wrist, E, has been heretofore used in said looms manufactured by the Draper Cointhe. hopper stand and .urrounds the bolt, B3,

Said bracket extends rearward and has at its rear end a and .is secured by said bolt.

hearing, G2', which is horizontal'a'ndA parallel to the ,magazine axis. ln said bearing is a rock shaft, G3. 0n the right hand end of said shaft 'is a finger, G, said shaft extending through said Finger and a set bolt, G5, extending through the base of the finger and binding the latter to said shaft. Said set I bolt permits the adjustment of said linger at different angles on said shaft.` Said finger is set to bear against the head of the slide bolt, B23, which is associated with the bobbin support, 312, as already described. A finger, Gr, is applied rigidly on the left hand end of said rock shaft and extends downward and rearward `in proper position to i'est immediately below-the upper trip pin when the'shuttle feeler is driven rearward to its rear limit-the position which it occupies when thefilling thread is to be clamped and parted or cut and when the bobbin is to be discharged from the magazine. A coiled spring, G7, surrounds the right hand 4portion of the bearing, G2, and has oneend extending beneath the bracket, G1, and the other end beneath ltheiinger, G4, for yieldingly pressing said finger upward toward or Aagainst'the head of the slide bolt, B23. In the left hand portion of the bearing, G2, is a `notch, G8, and a pin, G, is set rigidly on the .rock shaft, G3, within said notch. The notch vis of proper width toallow the desired partial rotation of said shaft and no' more.

Now Athe downward movement of such bobbin on the bobbin support will tilt the latter and drive the slide bolt, B23, against the finger, G4, driving the latter downward and turning the rock-shaft, G3, and raising the finger, G, whereby the upper trip pfin'is raised and theupper knife tilted to clamp the thread and bring the cutting edge of said knife'down upon the cutting edge of Athe lower knife. Then, as already described,

' fore the lower bobbin leaves 'the shuttle.

Furthermore, since the head ofthe transferrer moves downward rapidly, it follows that, as is desirable, a quick movement is imparted to the upper knife.

The thread holder arm, E26', serves in the usual way to support the illing thread until the latter hasl been clamped and parted or cut bv theknives already described and also by tlie temple knivesl at the'selvage` of the cloth.

As is the case in machines now in use, the

bobbin discharge path extends downward between the bobbin guide, B18, and the bobbin support, B19, and through a portion of the lattejr, and through and below the shuttle' and, as above indicated, thel bobbin support is a movable member extending into said path far enough to support the out--.

going magazine bobbin until the time for-` its discharge, and while the bobbin is travei'sing the discharge path, said movable member transmits motion to the filling thread clamping and parting instrumental-` ity or cutter. 1Normally, each bobbin traverses the entire discharge path froniftlie,4

i lowerinost position in theinagazine throughI the shuttle intoa receptacle used for` ije-g ceivingl the empty or rejected bobbins,1each bobbin remaining in the shuttle until nearly,

all of the thread on said bobbin into the cloth.
